NAILING-MACHINE.

SPECIFICATION' forming part of Letters Patent No. 240,332, dated April19, 1881.

Application tiled June 21, 1880.

To all whom it may concern:

Beit known that I, GEORGE H. PERKINS, of Philadelphia, Pennsylvania,have invented an Improved Machine for Nailing Boxes, ot' which thefollowing is a specification.

My invention relates in general to the class of mechanisms which areemployed to automatically and continuously drive nails into material tobe united; but it relates more specitically to the class of mechanismsemployed to nail together wooden boxes, such as are employed in theincasing of petroleumcans and the like. It is adapted, however, to thenailing together of various kinds of material.

Of the drawings, Figure l is a central sectional side elevation of amachine embodying my invention; Fig. 2, a front elevation ofthe same;Fig. 3, a top-plan sectional view ofthe same, on the line a.' a of Fig.1; Fig. 4, a sectional side elevation ot' a nail-holder and naildriverinvented by me and forming the subject-matter of an application forpatent, signed upon the same day and filed contemporaneously with thisapplication, and denominated by lne Case A; Fig. 5, a front elevation ofthe saine.; Fig. 6, a top sect-ion on the line b b of Fig. 4.

In my present apparatus a reciprocating cross head operated from adriving crankshaft has connected with it a series ofconnectingrods,which are each secured to a wristpin connected with aseparate plunger-carrier, each connecting-rod being separate from everyother, and being adapted to operate its individual plunger-carrier inwhatever position or inclination the latter may have been placed.

In the above construction my present apparatus diiers broadly from anyprevious boxnailing machine in that said `construction enables thedriving of nails at angles either opposite, varying, or coincident.

In the drawings, A A are vertical standards, constituting the sides ofthe frame-work of the machine, and united together above in a transversehead-bar, B. Below they spread out to form a base, O, of suitableconfiguration to support in bearings D a driving-axle, E, operated by adriving-pulley, F, and provided with a crank, Gr, to the wrist-pin ofwhich is secured a pitman, H, passing vertically upward to a crosshead,I, to which it is secured by a pivot-pin, J. It is obvious that therevo- (No model.)

lution ot' the axle will cause the reciprocntion ot' the cross-head.

K is a treadle in the base of the frame-work, connected with a clutchdevice, L, known as the Bliss clutch, ot' such familiar"construction toall mechanics as not to require explanation here. The operation oftheclutch is to throw the driving-pulley into and out of gear alternatelyat the beginning and end ot' each reciprocation of the plunger, itsaction being regulated by the treadle.

M are ways secured to the face-plate N of the machine, in which thecross-head plays.

In front of the face-plate is the table O, upon which the box to benailed is su pported, adapted to be raised or lowered to the properadjustnient by means otl screw-shafts P, to which it is threaded and bywhich it is supported, said shafts being operated by a bevel-gear, Q, inthe base 'ot' the frame-work.

R are connecting-rods, a series of which,

corresponding in number to the number ot" nail-holders, is employed.They are cach separately pivoted to the cross-head. These connecting-rods extend upward and attach to wrist-pins projecting from theplunger-carrier of each nail-holder, and are adapted to be adjusted withany lateral adjustment ot' the nailholders, or with any inclination ot'the same, so that they act invariably, upon the reciprocation of thecross-head, to operate the plungers, in whatever position the latter mayhave been placed.

The nail-holders represented in fourth, fifth, and sixth views of thedrawings constitute the subject-matter of an application iiled by me (asOase A) -contemporaneously with this, as hereinbetore referred to.

The separate connecting-rods B of my machine are each attached to aseparate wrist-pin, f, connected with the plunger-.carriers of saidnail-holders. These nail-holders consist, essentially, of acarrier-guide, within which a plunger-carrier, e, travels. Thecarrierguide is adapted, by means of a clamp-plate, c, or similardevice, to be set at varying lateral angles upon the frame-work.Depending from the carrier-guide is the nail-holder proper, m, a tubularreceptacle'incasing a pressure-spring, p, and adapted to lift upwardlyand backwardly as the plunger forces the nail from it.

IOO

The nail-holder is secured to the plunger-guide in the direct line ofthe stroke of the plunger and assumes the same angle with thecarrierguide.

Such being the construction of my invention, it is obvious that when thebox is placed upon the table or bed, the machine thrown into action, andeach of the plungers thereby caused to advance, the nails,one ot' whichhas been fed into each nail-holder, Will be driven into the material tobe united, at whatever inclination the nail-holders may have beenpreviously set, and as the machine is capable of adjustment with respectto its nail-holders, each independently of the other, it is obvious thatthe fastening ofthe box by varied inclination of the nails maybe madeextremely' secure.

Any number ot' nail-holders may, of course, be applied, theirapplication to the cross-bars of the machine being extremely simple, andthe reciprocating cross-head being best constructed With a large numberof pivots, so as to adapt it to receive a large number ot'connecting-rods.

The advantages incident to my machine are, that it enables theemployment of the Bliss clutch, thus dispensing` with the use ot' otherelaborate clutches, or clutches which may be uncertain in theiroperation; that it enables the omission ot' sectors and other kindreddevices to drive the plungers, and enables the employment of a pullingmechanism which acts direct upon the plunger-carriers from the cross-barwithout any intermediate mechanisms other than connecting-rods; that theaction ofthe crank and pitmau in the operation of pulling down thecross-head and its series of connecting-rods attached to thenail-plungers is both simple and certain 5 and that the employment ofthe nail-holders enables, as heretofore stated, the angular driving` ofthe nails, and imparts to the machine all the advantages which areincident to the nail-holder, as described in the application for patent,which I have made for the same.

Havin g thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. In a machine for nailing boxes,the combination ot' a reciprocating cross-head, a series of independentplungers, and a series of independent connecting-rods, one'end of eachof which is connected with the cross-head, and the other end of each otwhich is connected with a separate plunger, substantially in the mannerdescribed,r so that the downward pull of the cross-head, acting throughthe separate connecting-rods, operates the plungers, substantially asdescribed.

2. In a machine for nailing boxes, the combination of a reciprocatingcross-head, operated as described, With a series of' angularly andseparately adjustable plungers, by means of a series of separateconnecting-rods, whereby the downward pull of the cross-head, actingthrough the separate connecting-rods upon the separately-adjustedplungers, causes the driving ofthe nails at angles corresponding tothose at which the plungers have been disposed, substantially as shownand described.

In testimony whereof I have hereunto signed my name this 1st day of May,A. D. 1880.

GEORGE H. PERKINS.
